Compound Cinnamyl alcoholwith free spectra: 3 NMR, and 4 FTIR. Described here is the nucleophilic substitution of a hydroxyl group, in cinnamyl alcohol, by fluorine, and analysis of the product using 19-F NMR spectroscopy. This experiment brings important innovations to the teaching of experimental organic chemistry at the undergraduate level.

Due to the low levels found in cinnamon, cinnamyl alcohol is usually supplied as [DB14184] within commercial products. Cinnamyl alcohol has been shown to be a skin sensitizer, with a NOEL (No Effect Level) of ~4%. Compound Cinnamyl alcoholwith free spectra: 2 FTIR, and 1 Raman.
